Physicians are also responsible for the increase in sexually transmitted infections. We report a case of patient inadequately monitored, that shows the importance of physicians to take basic measures with any individual at risk of acquiring such infections. We propose the following mnemonic acrostic: PRO-LIVES (Protection: usual and proper codom use, Responsibility, Other orientations, Laboratory tests -HIV infection, syphilis and B and C hepatitis-, Immunization: B hepatitis vaccination, Various: at least two patients, Ensure: case history and physical examination, Single dose treatment: whenever possible)...

We conducted a critical review of the literature on recurrent use of HIV testing in men who have sex with men (MSM). We performed a narrative review of the literature in which we analyzed the various conceptions on frequent testing over time, the implications for health programs, and the main social markers that influence the incorporation of HIV testing as routine care. Although it has existed since the 1990s, recurrent testing among MSM was frequently interpreted as increased exposure to HIV due to lack of condom use, and therefore as "unnecessary" testing...

This economic evaluation aims to support policy-making on the combined use of pre-exposure prophylaxis (PrEP) with HIV vaccines in development by evaluating the potential cost-effectiveness of implementation that would support the design of clinical trials for the assessment of combined product safety and efficacy. The target study population is a cohort of men who have sex with men (MSM) in the United States. Policy strategies considered include standard HIV prevention, daily oral PrEP, HIV vaccine, and their combination...

Enveloped viruses have evolved diverse transmembrane proteins and protein complexes to enable host cell entry by regulating and activating membrane fusion in a target cell-specific manner. In general terms, the entry process requires a receptor binding step, an activation step and a membrane fusion step, which can be encoded within a single viral protein or distributed among multiple viral proteins. HIV and influenza virus, for example, encode all of these functions in a single trimeric glycoprotein, HIV env or influenza virus hemagglutinin (HA)...

OBJECTIVE: There is inconsistent evidence that zidovudine use during pregnancy increases overall, cardiac, and male genital malformations. DESIGN: We conducted a systematic review and meta-analysis of zidovudine use and malformations and, using Bayesian methods, combined it with data from a cohort study of mother-infant pairs in the nationwide Medicaid Analytic eXtract (MAX). METHODS: Using MAX data (2000-2010), we identified pregnant women with HIV treated with antiretroviral therapy (ART)...

: There is a long-lasting controversy surrounding an association between Abacavir (ABC) and an increased risk of cardiovascular (CV) disease in HIV-positive subjects. While differing in their specifics, a number of published cohort studies and clinical trials support such an association, usually relating it to recent exposure to the drug, independently of traditional predisposing factors. However, other clinical trials have failed to reveal such a relation, and have pointed to methodological differences to explain discrepancies...

The House and Ball community is an important cultural manifestation of resiliency for Black and Latino gay and bisexual men and transgender women. Participants at the August, 2013 House of Latex Ball in New York City were surveyed about insurance coverage, health care access, experiences in health care, and housing instability. The sample (n = 367) was 58% Black/African American and 20% Hispanic/Latino, with a mean age of 31. Fifty-five percent were gay and bisexual men. While only 6% identified as transgender, nearly half were gender nonconforming...

Retroviral and lentiviral vectors are mostly pseudotyped and often purified and concentrated via ultracentrifugation. In this study, we quantified and compared the stabilities of retroviral [murine leukemia virus (MLV)-based] and lentiviral [human immunodeficiency virus (HIV)-1-based] vectors pseudotyped with relatively mechanically stable envelope proteins, vesicular stomatitis virus glycoproteins (VSVGs), and the influenza virus WSN strain envelope proteins against ultracentrifugation. Lentiviral genomic and functional particles were more stable than the corresponding retroviral particles against ultracentrifugation when pseudotyped with VSVGs...

The introduction of highly active antiretroviral therapy marked a major gain in efficacy of HIV/AIDS treatment and a reduction in morbidity and mortality of the infected patients. However, high levels of adherence are required to obtain virologic suppression. In Brazil, the policy of free and universal access to antiretroviral therapy has been in place since 1996, although there are reports of poor adherence. OBJECTIVE: To define the clinical, demographic and psychological characteristics, and quality of life of patients with HIV/AIDS who present poor adherence to highly active antiretroviral therapy...

The acquired immune deficiency syndrome (AIDS) epidemic was first recognized in 1981, and it quickly became a public health emergency. In a 1987 paper in the American Journal of Epidemiology (Am J Epidemiol. 1987;126(2): 310-318), Richard Kaslow et al. described the launch of the Multicenter AIDS Cohort Study (MACS), a cohort study of homosexual men in 4 US cities, the purpose of which was to better understand the natural history of AIDS and its determinants. The MACS enrolled participants through a range of community contacts...

Background: HIV-1 persists in latently infected resting CD4+ T cells (rCD4), posing a major barrier to curing HIV-1 infection. Previous studies have quantified this pool of latently infected cells in Americans; however, no study has quantified this reservoir in sub-Saharan Africans, who make up the largest population of HIV-1-infected individuals globally. Methods: Peripheral blood was collected from 70 virally suppressed HIV-1-infected individuals from Rakai District, Uganda, who had initiated antiretroviral therapy (ART) during chronic infection...

Next-generation sequencing prototypes for the routine diagnosis of resistance to antiretrovirals approved for the treatment of HIV infection are now being used in many clinical diagnostic laboratories. As some of the next-generation sequencing platforms may be a source of errors, it is necessary to improve the currently available protocols and implement bioinformatic tools that may help to correctly identify the presence of resistance mutations with clinical impact. Several studies have addressed these issues in recent years...

Long-term experience in the treatment of HIV-infected individuals has shown indirect benefits of early initiation of antiretroviral therapy, particularly in preventing HIV transmission. With the advent of direct-acting antivirals for the treatment of hepatitis C, the strategy of treatment-as-prevention has become feasible. However, economic, clinical, ethical, and public health issues arise from the concept of using therapeutic interventions only as prevention strategies.

Hypertension is among the leading risk factors for cardiovascular disease and accounts for 6% of adult deaths worldwide. It is estimated that in 2013, hypertension was responsible for at least 45% of deaths due to heart disease and 51% of deaths due to stroke. Accordingly, management of hypertension and its long-term complications in HIV-infected subjects is a significant component of routine care. The choice of an effective anti-hypertensive therapy in HIV-infected patients is important and must be made carefully in order to prevent cardiovascular mortality and morbidity in these patients...

CC-chemokine receptor 5 serves as the coreceptor for the HIV-1 R5 strains, which are responsible for the majority of HIV transmissions. A deletion of 32 nucleotides in the gene encoding this receptor (termed CCR5-Δ32) leads to the suppression of CC-chemokine receptor 5 presentation at the cell surface, thus impeding process of HIV entry into the cell. Individuals homozygous for the CCR5-Δ32 allele are resistant to infection with HIV-1 R5 strains, and are extremely rare among HIV-1-infected individuals. We have described a case of person homozygous for CCR5-Δ32, who was infected with subtype B HIV-1...

Several strategies to reduce and control the HIV reservoir are being evaluating to achieve the great challenge of HIV remission or functional cure. Some of these are based on immune and gene therapy, or in the use of agents with latency reversing properties. Moreover, acute HIV infection and the impact of early antiretroviral treatment (ART) initiation is another key issue of current research. It has been demonstrated that ART initiation during acute HIV infection minimizes the establishment of the latent HIV reservoir...

Since the advent of triple combination antiretroviral therapy in 1996, the prognosis of HIV-infected persons has improved drastically. The clinical benefits of HAART derive from producing sustained viral load suppression and CD4 gains. The major drawbacks of the first HAART regimens were common adverse events and high pill burden, which resulted in difficult drug adherence and led to frequent discontinuations and selection of drug resistance.

People who inject drugs (PWID) and HIV-infected men who have sex with men (MSM) are key risk groups for HCV transmission. Mathematical modeling studies can help elucidate what level and combination of prevention intervention scale-up is required to control or eliminate epidemics among these key populations. We discuss the evidence surrounding HCV prevention interventions and provide an overview of the mathematical modeling literature projecting the impact of scaled-up HCV prevention among PWID and HIV-infected MSM...
